CVE-2026-123561
devalue before 5.9.3 allows malformed null-prototype object keys to bypass parse's proto rejection through property-key coercion, an incomplete fix for GHSA-mwv9-gp5h-frr4. Attackers can supply crafted payloads that yield objects with a proto own property, which alone does not cause prototype pollution.
